Balanced equation of potassium chloride and ammonium nitrate; it’s types, net and observation
ASHA 777 [7]

Potassium chloride reacts with ammonium nitrate to give ammonium chloride and potassium nitrate.

This is a type of double displacement reaction. The balanced chemical equation can be represented as,

KCl(aq)+NH_{4}NO_{3}(aq)-->NH_{4}Cl(aq)+KNO_{3}(aq)

Total ionic equation for this reaction will be,

K^{+}(aq)+Cl^{-}(aq)+NH_{4}^{+}(aq)+NO_{3}^{-}(aq)--> K^{+}(aq)+NO_{3}^{-}(aq)+NH_{4}^{+}(aq)+Cl^{-}(aq)

There is no apparent reaction as this reaction is not accompanied by the formation of a gas or a solid precipitate. We cannot observe any visual reaction as there is not net reaction taking place. All the ions remain as spectator ions.

Water ionizes by the equationH2O(l)⇌H+(aq)+OH−(aq)The extent of the reaction is small in pure water and dilute aqueous solutions
tia_tia [17]

Explanation:

H_2O(l)\rightleftharpoons H^+(aq)+OH^-(aq)

The value of K_w :

K_w=[H^+][OH^-]

a. pOH = 3.51

The sum of pH and pOH is equal to 14.

pH + pOH = 14 (at 25°C)

pH = 14 - 3.51 = 10.49

The pH of the solution is defined as negative logarithm of hydrogen ion concentration in solution.

pH=-\log[H^+]

10.49=-\log[H^+]

[H^+]=3.2\times 10^{-11}

3.2\times 10^{-11} Mis the H^+ concentration for an aqueous solution with pOH = 3.51 at 25°C.

b.

At a certain temperature, the pH of a neutral solution is 7.56.

Neutral solution means that concentration of hydrogen ion and hydroxide ions are equal.

[H^+]=[OH^-]

7.56=-\log[H^+]

[H^+]=2.754\times 10^{-8} M

The value of K_w at at this temperature:

K_w=[H^+][OH^-]

K_w=[H^+][H^+]

K_w=(2.754\times 10^{-8})^2=7.6\times 10^{-16}

The value of K_w at at this temperature is 7.6\times 10^{-16}.
